Credit Agricole is a powerful French bank in the world. Its actual organisation and structure is based on the development of Local and National Banks. This particular development is the base of the success of the brand. The group is well developed and well established on the international market, more over in the field of personal accounting. This structure has made the brand successful on the market, but it has also developed disadvantage in the proximity to its customers. The problem is due to a lack on the computer system to centralize all data. Actually, the computer system of each bank is separate and there is no link between all the banks and branches of the group. So the result is for example, Customers of the Credit Agricole Centre Est don't have any access to their account in other regions of France, and around the world. They can only consult their account in the region where they are registered. That is why the company wants to develop a new system on its cash dispenser to merge all computer system in each branch, and to offer this providing service.
